The three virtues of a programmer: Laziness, Impatience, and Hubris. – Larry Wall
Legacy:Built-In Structs (UT)
From Unreal Wiki, The Unreal Engine Documentation Site
These structs are declared in Object and can be used everywhere in UT's UnrealScript. Many of these have operators defined for them.
See Built-In Struct for the UT2003 built-in structs.
Contents |
GUID
A globally unique identifier.
struct Guid
{
var int A, B, C, D;
};
Vector
A point or direction vector in 3d space.
struct Vector
{
var() config float X, Y, Z;
};
See Useful Maths Functions for some useful vector assignment operators.
Plane (extends Vector)
A plane definition in 3D space. See Plane.
struct Plane extends Vector
{
// inherited: normal vector X, Y, Z
var() config float W; // distance from origin
};
This could also be used to describe a sphere: X, Y, Z is the location of the sphere's center and W is the radius.
Rotator
An orthogonal rotation in 3d space. See Rotator.
struct Rotator
{
var() config int Pitch, Yaw, Roll;
};
Coords
An arbitrary coordinate system in 3d space.
struct Coords
{
var() config vector Origin, XAxis, YAxis, ZAxis;
};
Scale
A scale and sheering.
struct Scale
{
var() config vector Scale;
var() config float SheerRate;
var() config enum ESheerAxis
{
SHEER_None,
SHEER_XY,
SHEER_XZ,
SHEER_YX,
SHEER_YZ,
SHEER_ZX,
SHEER_ZY,
} SheerAxis;
};
Color
An RGB color.
struct Color
{
var() config byte R, G, B; // red, green, blue color components
var() config byte A; // alpha component
};
See also the page on custom Color Operators.
Note that many functions and class variables don't use this struct for colours, eg ZoneInfo's ViewFog.
BoundingBox
A bounding box.
struct BoundingBox
{
var vector Min, Max;
var byte IsValid;
};
BoundingVolume
A bounding box sphere together.
struct BoundingVolume extends BoundingBox
{
var plane Sphere;
};
